技术领域 technical field
本实用新型涉及一种配电柜防爆泄压装置，属于工业配电安全防护技术领域。 The utility model relates to an explosion-proof pressure relief device for a power distribution cabinet, which belongs to the technical field of industrial power distribution safety protection.
背景技术 Background technique
配电柜是电气控制，通讯等领域使用的重要设备，中压配电柜一般都设计出在故障情况下爆炸的泄压装置及释压通道，所以爆炸泄压装置是柜体必须的配置，尤其是中高压柜体在保障操作人员的生命安全方面起着重要作用。目前，背景技术存在的问题是：柜体虽有泄压装置，但不能保证泄压板及其爆炸物被阻挡在柜体内部，这样很可能飞出伤到现场工作人员。 Power distribution cabinets are important equipment used in electrical control, communication and other fields. Medium-voltage power distribution cabinets are generally designed with pressure relief devices and pressure relief channels that explode in the event of a fault, so the explosion pressure relief device is a necessary configuration for the cabinet. In particular, medium and high voltage cabinets play an important role in ensuring the safety of operators. At present, the problem existing in the background technology is that although the cabinet body has a pressure relief device, it cannot ensure that the pressure relief plate and its explosives are blocked inside the cabinet body, which is likely to fly out and injure the on-site staff.
实用新型内容 Utility model content
本实用新型目的是提供一种配电柜防爆泄压装置，中压柜爆炸后飞出物被阻隔，不影响到泄压，更好的保护现场工作人员的生命安全，解决背景技术中存在的上述问题。 The purpose of the utility model is to provide an explosion-proof pressure relief device for a power distribution cabinet. The flying objects after the explosion of the medium voltage cabinet are blocked, which does not affect the pressure relief, better protects the life safety of the on-site workers, and solves the problems existing in the background technology. above question.
本实用新型的技术方案是：一种配电柜防爆泄压装置，包含柜体、泄压板、防护罩，泄压板设置在柜体的顶部，防护罩设置在泄压板的上方。 The technical scheme of the utility model is: an explosion-proof pressure relief device for a power distribution cabinet, including a cabinet body, a pressure relief plate, and a protective cover. The pressure relief plate is arranged on the top of the cabinet body, and the protective cover is arranged above the pressure relief plate.
所说的防护罩由后封板、上通风板、中通风连板、前封板、下通风板组合而成，后封板和前封板安装于柜体之上，相当于支架，上通风板、中通风连板、下通风板上均设计通气孔，上通风板与下通风板交错安装于中通风连板上，再与后封板及前封板连接成整体。 The protective cover is composed of the rear sealing plate, the upper ventilation plate, the middle ventilation connecting plate, the front sealing plate and the lower ventilation plate. Ventilation holes are designed on the board, the central ventilation connecting plate and the lower ventilation plate. The upper ventilation plate and the lower ventilation plate are alternately installed on the middle ventilation connecting plate, and then connected with the rear sealing plate and the front sealing plate to form a whole.
上通风板、中通风连板、下通风板相互交错安装，构成互交错式的迷宫结构，防尘、通气性能好。后封板、前封板与柜体的外形结构尺寸相匹配，保证不用改变原柜体尺寸。上通风板、下通风板的结构形式为整体钢板冲制折弯而成，当柜体联拼时泄压通道可通过下通风板连起来发挥更大压力释放空间特点；后封板、 中通风连板、前封板侧边均采用于拉铆螺母用的圆形沉坑，当柜体联拼时解决了螺栓干涉的麻烦。 The upper ventilation plate, the middle ventilation connecting plate and the lower ventilation plate are installed alternately to form an interlaced labyrinth structure, which has good dustproof and ventilation performance. The rear sealing plate and the front sealing plate are matched with the external structure size of the cabinet to ensure that the original cabinet size does not need to be changed. The structure of the upper ventilation plate and the lower ventilation plate is formed by punching and bending the whole steel plate. When the cabinets are joined together, the pressure relief channel can be connected through the lower ventilation plate to exert the characteristics of greater pressure release space; the rear sealing plate and the middle ventilation Both the connecting plate and the side of the front sealing plate are made of circular sinkholes for rivet nuts, which solves the trouble of bolt interference when the cabinets are combined.
本实用新型的有益效果是：本实用新型是防止当泄压板被炸开后的飞出物以及泄压板本身被炸飞的装置，可以最大程度的降低的现场人员的危险；中压柜爆炸后飞出物被阻隔，不影响到泄压，更好的保护现场工作人员的生命安全。 The beneficial effects of the utility model are: the utility model is a device for preventing the flying objects and the pressure relief plate itself from being blown away when the pressure relief plate is exploded, and can reduce the danger of the on-site personnel to the greatest extent; Flying objects are blocked and do not affect pressure relief, which better protects the safety of on-site staff.
